1 Claim. (Cl. 20-55) This invention relates to auxiliary windows and particularly to the mounting thereof on existing windows of the double hung type.

In my prior Patent No. 2,514,349, patented July 4, 1950, there is disclosed an auxiliary window mounting which enables auxiliary sash such as storm sash or screen sash to be mounted in position on double hung frames without the necessity for providing complete supplemental mounting frames therefore, the sash as disclosed in my aforesaid patent being wood frame sash that are supported in what may be termed a double hung relationship with an upper sash and a lower sash disposed in an overlapping relationship of the general nature employed in double hung windows.

It has been found that the general arrangement of the sash as disclosed in my aforesaid prior patent is highly effective in use and has particular appeal to home owners because it enables the sash to be supported in a way that does not change or objectionably modify the appearance of the windows of the building.

The present invention is concerned with attainment of an auxiliary window sash mounting quite similar in its basic aspects to the arrangement disclosed and claimed in the aforesaid prior patent, but under the present invention the mounting elements that are required have been materially simplified and reduced in number so as to reduce the amount of material required for such mounting elements, and in addition, these mounting elements have under the present invention been so formed and related to the sash that are to be mounted that the installation of the mounting members may be accomplished more readily than the mounting means that are disclosed in my aforesaid prior patent. v

The primary objective of the present invention is to simplify the installation and mounting of auxiliary sash so that such sash may be readily and accurately installed by a home owner who is not particularly skilled in the mechanical arts, and a related objective is to provide mounting members that are readily positioned in the proper relation-ship with respect to the parts of a window frame so that the time required in making a window installation will be minimized.

Other and further objects of the present invention will be apparent from the following description and claim and are illustrated in the accompanying drawings which, by way of illustration, show a preferred embodiment of the present invention and the principles thereof and what I now consider to be the best mode in which I have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention.

Fig. 19 is a sectional view of one edge of a sash, the g ewllgaeing taken substantially along the line 19-19 of For purposes of disclosure the invention is illustrated herein as embodied in a conventional double hung window 20 that is equipped with auxiliary sash 21 and 22 in accordance with the invention. The window 20 has the conventional wood frame providing jamb members 23, a head 24 and a sill 25, and the head 24 and jamb members 23 have the usual stops including outer stops 24S and 238 that provide for vertical sliding mounting of the usual wood sash S. Outer trim members 123 and 124 cooperate in the usual manner with the outer stops 23S and 248 to afford the usual horizontal blind seat and the usual vertical blind seats, such relation being important in that the upper auxiliary sash 21 is mounted in such blind seat so as to abut against the outer faces of the outer stops 23S and 24S.

The auxiliary sash 21 and 22 are illustrated as being storm sash, but it will be recognized that such sash may also be constituted as screen sash within the purview of this invention. Such sash may be either wood-framed, as shown for example in my prior Patent No. 2,514,349, patented July 4, 1950, or metal framed, as shown for example in my prior Patent No. 2,666,508, patented January 19, 1954, and under the present invention the general theories of dimensional relationship and relative positioning of the auxiliary sash that are disclosed in my aforesaid Patent No. 2,514,349 are utilized in a simplified and more economical mounting means that particularly adapt the present invention for use and installation by home owners, as will be described hereinafter.

As herein shown the sash are formed from metal extrusions 30, Figs. 6 and 16 to 19, having undercut grooves 31 to receive corner brackets 32, and as described in detail in my aforesaid Patent No. 2,666,508, the brackets and extrusions are held together at the mitered corners by binder head screws 33 that clamp the arms of the brackets against the undersides of ledges 31L which form parts of the walls of the grooves 31. The glass panes P are seated in grooves .35 in the inner edges of the extrusions, and a plastic U-shaped seating strip 36 is preferably utilized in such mounting as shown in Fig. 19. Handles 37 may be provided on the lower rail of the lower sash 22 and may be mounted thereof by screws 38 extending through the handles and into bars 39 provided in the groove 31 of such rail. The lower rail of the upper sash 21 prefera'bly has a Weatherstrip along its inner face, and when sash of the kind described are used, this may be accomplished by anchoring a yieldable plastic Weatherstrip 40 in the groove 31 of this rail as shown in Fig. 6.

The lower sash 22 has a horizontal dimension slightly less than the distance between the outer stops 233, while the upper sash 21 has a horizontal dimension slightly less than the distance between the opposite sides of the blind seat, and this provides for mounting of these sash respectively on the stops 23S and in the blind seat, as will now be described. Thus under the present invention, but three mounting members are required, the upper mounting member 41 serving as a part of the retaining means for the upper sash 21, and the two lower mounting members 42L and 42R serving not only to mount and retain the lower sash 22 but also to cooperate with the upper mounting member 41 in retaining the upper sash 21 in position.

The upper mounting member 41 is in the form of a facia that is-provided by a sheet metal angle having a horizontal upper flange 41H having a depending vertical flange 41V along its outer edge. The flange 41H has a width substantially equal to the frame thickness of the sash 21, and this member 41 has a length substantially equal to the distance between the trim members 123. The member 41 is mounted in the upper or horizontal portion of the blind seat by positioning the edge of the flange 41H against the outer face of the outer stop 24 as shown in Figs. 6 and 11 and securing the same in position by nails 43. The upper edge of the sash 22 may thus be inserted upwardly into the space between the outer stop 24 and and the flange 41V, as shown in Fig. 6, and when this is done a plurality of springs 44, that form part of the member 41, are compressed for purposes that will appear hereinafter. The springs 44 as herein shown are in the form of convex bow springs anchored by rivets 45 at one end on the lower face of the flange 41H, Pig. 9, and rounded at 44R at their other ends to facilitate compression of the springs.

The two lower mounting members 42R and 42L are generally similar in form but are made as right and left hand embodiments of the same basic form, as will become apparent hereinafter. Thus each of the lower mounting members is channel-like in form and is made from sheet metal to provide a web 42W, and inner and outer flanges 142 and 242, Figs. 14 and 15. The inner flanges 142 are cut away at their upper ends as at 142C to enable insertion of the lower sash to be accomplished from the inside of the dwelling. At the upper ends of the outer flanges 242, support brackets 47 are fixed so that the lower edges of the upper sash 21, thus to hold the upper sash 21 in proper engagement with the upper retaining member 41. The support brackets 47 are formed from sheet metal to provide a horizontal shelf 478 with a downwardly projecting attaching flange 47F, Figs. 14 and 15, and an upwardly projecting retaining flange 47R along its other edge. The mounting flange 47F is secured to the outer face of the flange 242 of the channel by a rivet 48, and the bracket 47 is of such a length as to pro- 4. ject beyond the web-side of the flange 242, as shown in Figs. 14 and 15. In the projecting end of the flange 47]? an opening 147 is provided to simplify installation of the members 42R and 42L as will hereinafter appear.

Within the channels 42R and 42L, a plurality of springs 54 are provided at spaced points, and these springs have the same form as the springs 44, and are secured to the webs 42W by rivets 55. These springs serve to center the lower sash 22.

After assembly of the sash 21 and 22, the installation of the mounting elements is readily and easily accomplished. Thus, the upper mounting member 41 is nailed in position, as described, and the engagementof the flange 41H thereof with the outer stop 24 assures that the proper location of the member 41 may be easily determined.

The lower mounting members 42R and 42L are then installed on the respective outer stops 23, and in such installation the brackets 47 extend laterally along the outer faces of the stops 23, as shown in Figs. 1, 3 and 8, thus to assure proper location of the upper ends of the members 42R and 42L with respect to the stops 23 and the blind seat. The members 42R and 42L are fixed in place by nails 57 driven through the openings 147 into the outer stops 23, and by nails 58 driven through preformed holes 59 in the webs 42W and into the stops 23.

The upper sash 21 may then be put in place from the inside of the dwelling by opening the lower sash S, and working through the open lower half of the window to engage the upper sash 21 with the member 41, and by compressing the springs 44 the lower edge of the sash 21 may be swung into position over the brackets 47. The upward pressure is then released, and the sash 21 is urged downwardly behind or inwardly of the retaining flanges of the brackets 47 and onto the shelf portions thereof. Thus the upper sash 21 is held firmly in position, and by engagement with the stops 23 and 24, is sealed about its upper and side edges.

The lower sash 22 is then put in position by inserting its upper edge upwardly between the upper sash 21 and the meeting rail of the upper main sash. Such upward inserting movement is continued until the lower edge of the sash 22 is above the upper end edges 1420 of the flanges 142, and the lower edge of the sash 22 is then forced outwardly to align the sash with the channels of the members 42L and 42R. The sash 22 is then lowered into these channels so as to rest on the sill 25, and when this is done the upper rail of the sash 22 engages the Weatherstrip 40, as shown in Fig. 6.

With the mounting means that are thus afforded, the auxiliary sash may be mounted on an existing double hung window frame with the minimum of effort, and by reason of the particular form and arrangement of such mounting means, the installation thereof is attained with considerable accuracy of location of the parts on the window frame. The simplicity of these mounting elements adapts the same for marketing as a part of what may be termed a kit which may include those elements illustrated in Figs. 16 and 17 of the drawings. Thus, the home owner may utilize such a kit to assemble the sash that are required, and may mount such sash on the window frame with the minimum of effort. Once the mounting elements have been put in place on the window frame, the owner may utilize the same to support eithcr storm sash or screen sash, and if only a half-screen arrangement is desired, the half-screen may be mounted in the lower mounting members 42L and 42R in the position of the sash 22 as illustrated herein, and such a screen thus cooperates with the meeting rail of the upper sash to afford the desired closure of the opening against the entry of insects.

From the foregoing description it will be apparent that present invention materially simplifies the installation of auxiliary sash, and that this is accomplished by means that are simple and economical in character and which may be mounted quickly and easily in the desired accurate relationship with respect to a window frame.

Thus while I have illustrated and described a selected embodiment of my invention, it is to be understood that this may be altered and modified by those skilled in the art without departing from the spirit and scope of the invention.
